完全ガイド: PDFをマージ

Merging PDF files is one of the most common document management tasks in both professional and personal contexts. Whether you're compiling reports for a business meeting, combining scanned documents into a single archive, or putting together a portfolio of your work, having a reliable PDF merger is essential. iLoveDoc's Merge PDF tool processes everything directly in your browser using advanced JavaScript libraries, which means your sensitive documents never leave your device. Unlike cloud-based alternatives that upload your files to remote servers, our local processing approach guarantees complete privacy and eliminates any risk of data breach. The merge process preserves the original formatting, hyperlinks, bookmarks, and image quality of each source file. You can combine PDFs of different page sizes, orientations, and even those with form fields or digital signatures. There's no limit on the number of files you can merge or their total size — your browser's memory is the only constraint. The drag-and-drop interface makes it easy to reorder files before merging, ensuring your final document flows exactly as intended. Once merged, the resulting PDF is instantly available for download with a single click. This tool is perfect for students compiling research papers, HR professionals consolidating employee records, lawyers assembling case files, and anyone who needs to organize multiple PDF documents into one cohesive file.

PDFをマージ に関するよくある質問

How many PDF files can I merge at once?

There is no hard limit on the number of files. You can merge dozens of PDFs in a single operation. The only constraint is your browser's available memory, but modern browsers handle hundreds of pages without issue.

Will merging affect the quality of my documents?

No. The merge process preserves every element of your original files — text, images, vectors, fonts, and formatting remain exactly as they were. There is zero quality loss.

Can I merge PDFs with different page sizes?

Yes, absolutely. You can merge documents with different page sizes (A4, Letter, Legal, etc.) and orientations (portrait and landscape). Each page retains its original dimensions in the merged file.

Are my files uploaded to a server during merging?

No. All processing happens locally in your web browser. Your PDF files never leave your computer and are never transmitted over the internet. This guarantees complete privacy and security.

Can I change the order of pages after merging?

Before merging, you can freely reorder files using drag-and-drop. If you need to reorder individual pages after merging, use our Organize PDF tool for fine-grained page management.

Does the merged PDF preserve bookmarks and hyperlinks?

Yes. Bookmarks, hyperlinks, form fields, and other interactive elements from the original PDFs are preserved in the merged document.
